Specification of Letters Patent.

Application filed January 6, 1921. Serial No. 435,549.

(GRANTED UNDER THE PROVISIONS OF THE A01 05 MARCH 3, 1921, 41 STAT. L, 1313.)

T 0 all whom it may concern:

Be it known that HENRY Rosa, deceased, a subject of the King of Great Britain, and resident of Albion YVorks, Gainsborough, England, invented certain new and useful Improvements in Machines or Apparatus for Wrapping Cakes or Blocks, Such as Caramels or Other Sweetmeats, and the like, (for which has been filed application in Great Britain May .28, 1919, Patent No. 150,076,) of which the following is a specification.

This invention relates to machines, or apparatus, for wrapping cakes, or blocks, such, for instance, as caramels, or other sweetmeats and the like, (which for brevity We will refer to as caramels) the said machines, or apparatus, being of the type in which the caramels are passed, with the wrappers, into recesses in a mould-wheel (capable of movements of partial rotation) whereby the wrappers are folded around three sides of the caramels, the wrapping of the fourth side being effected by movable and stationary folders and the final wrapping being effected by twisting, in the same direction, the projecting open ends of the wrappers'after which the wrapped caramels are removed by an ejector from the recesses in the mould-wheel.

This invention has for its objectto provide an improved machine, or apparatus, of the aforesaid type which will effect the wrapping more efiiciently and expeditiously than hitherto and consists mainly in the im" proved construction, arrangement and operation of the parts, as hereinafter described, whereby a portion of one of the outstanding ends of the wrapper is first folded onto the outer, or fourth, side of the caramel and the remaining portion of the said end is bent back upon itself and then this portion together with the other outstandingend of the wrapper are folded onto the first mentioned portion so that, at the said outer or fourth, side of the caramel there are three superposed layers of wrapping material which conjointly act to more effectually prevent dust, or the like, gaining access to the caramel between the lapped portions of the wrapper as the twisting of the ends tends to hold the bent-back or midportion, of the wrapping material in close contact with the outer portion. A yieldable presser acts to hold the folded ends of the wrapper in position on the caramel whilst the aforesaid twisting is being effected.

The mechanism by which the mould-wheel is operated may be of the well known Geneva kind usually employed in machines, or apparatus, of the aforesaid type and the material for the wrappers (which we will presume to be paper) may be supported in the form of a rotatable roll and be led over guides and fed intermittently to cutters as usual. If the cutting be effected 'before the caramel has pushed its portion of wrapping paper into the recess on the mould-wheel, a stop will be provided at a distance from the cutters in accordance with the length required for the wrappers.

The paper may be guided in anyv suitable way, it being preferably kept taut by being passed beneath a jockey-roller, or rod, capable of rising and falling, the paper being then brought upwards and passed over a roller. and then down between rollers one of which is driven intermittently to accord with the intermittent movements of the mould-wheel which movements will bring the recesses therein successively into proper positions for the reception of the papers and the caramels, and for the subsequent wrapping operations.

A pressure roller is preferably provided for giving a grip on the paper-feeding roller, the said pressure roller being carried by an arm so that it can be raised and held away from its associate roller, which can then rotate inoperatively. The caramels are fed into a trough provided with an endless belt, or band, or chain caused to travel intermittently to convey the caramels to a position opposite. the paper in a pocket or space, which may be between guide-plates with openings therein in line with a recess in the mould-wheel when a pusher pushes thecaramel and paper through the openings in the guide plates and into the recess in the mouldwheel the caramel being thus covered on three sides by the paper the outer edges of which stand out beyond the periphery of themould-wheelto a sufficient extent to provide material to fold over the outer, or fourth, side and encircle the caramel com- Patented May 2, 1922.

pletely and to overlap to any desired extent, the paper also extending on either side ot the mould-wheel to asuiticient extent to allow for twisting to complete the wrapping, or enclosure, of the caramel. The aforesaid openings in the pocket, or plates, for the paper act as guides to control the paper when being pushed along with the caramels into the recesses in the mould-wheel and assist in creasing the paper as required. The opening in the first guide-plate is of a width and length which will allow of the pushing therethrough of the caramel from the belt, or band, or chain, into the recess in the mouldwheel, the opening. in the second guide-plate being of a length which will allow the whole Width of the wrapper to pass throughand the portions which are to be subsequently twisted to project "from the recess in the mould-wheel. The mould-wheel then makes a partial rotation when the same operations on the succeeding caramel and paper are performed, this partial rotation oi the mouldwheel bringing the first lllGllt-lOllc/ll caramel and paper to a position in which the outstanding portions oi": the paper projecting beyond the periphery of the mouldwhccl are folded over the caramel, by a folder operated by any suitable means, which folds a portion of the rear outstanding end of the paper (which may be long enough to overlap'to any desired extent) onto the outer, or fourth, side of the caramel and then the remaining portion of the said rear end and the forward outstanding end of the paper pass under a stationary folder whereby they are both iolded onto the first mentioned .portion on the outer, or fourth, side of the caramel. The mould-wheel then mares a further partial rotation and an extension. from the aforementioned stationary folder, or other suitable part, which is fixed in a position concentric with the mould-wheel shaft, retains the paper in its iolded position until its ends which extend beyond the sides of the mould-wheel are twisted which coinpletes the w apping, or ioli'ling. lft the wrapper has a further overlapping portion, this can be folded down by a folder (operated by any suitable cam and connections) before the twisting operations. The

ing is effected by two sets of grippers wh can be mounted in bearings in the n. n

frames of the machine the jaws o the s. grippers being caused, by any suit means, to open and afterwards close t grip the projecting open ends oi the wrapper the said grippers being caused to have rotary movement for twisting. The grippers have also longitudinal movement towards each other to follow up the shorten-- ing of the ends of the paper due to the twisting. To ensure the proper gripping ot the paper a roughened ridge, or the li maybe provided on each gripper tace.

compensate for irregularity of the shape ot the caramels, the first folded ends of the "mapper should be under control while twisting is being performed. For this purpose we may provide a yieldable presser on the lower end of the extension from the stationary folder, the said presser bearing on the paper sufficiently to keep the caramel in proper position. @ne of the sides of each of the recesses in the mould-wheel may he yieldable and be controlled by a spring and by any suitable levers, one lever operating to allow the caramels to be pushed into the recesses in the mould-wheel and another lever operating to slightly release the caramels when the grippers are twisting the ends of the wrappers. A The bottom of each recess in the mould-wheel is connected to a sliding spindle and so operated, at the proper times, and in any suitable way, sons to eject the wrapped caramels from the recesses in the mould-wheel. The bottoms of the recesses may project from each side of the mould-wheel to assist in controlling the wrappers as they are being pushed, with the caramel, into the recesses in the mould wheel.

The accompanying drawings show ii ma chine comprising the improvements in accordance with the present invention, which is not limited however, to the precise details illustrated in the said drawings, and described with reference thereto.

Figure 1 is a side elevation, Figure section through theline 2, 2, Figure 1, Figure 3 a plan.

Figures 4: to 13, both inclusive, show, separately, details of the several. devices which constitute the main features of this invention, Figures 4: and 5 showing, in. elevation and transverse section, and in two ditterent positions, the devices by means of which the carai'nels are fed into the recesses in the mould-wheel, Figures 6 and 7 showing, in end elevation, partly in section, and in two ditl'erent positions, the devices for tolding the wrappers around the caramels. means for holding the wrapper in position on the caramel, and means "for ejecting the completely wrapped caramel from the recess in the moul-dwheel, F igures 8 and 10 showing in side elevation, and Figures 9 and 11 in plan, also in two different positions, the devices for twisting the ends of the wrappers which have been folded around the caramels, whilst Figures 12 and 13 show, in two different positions, a device by which the grippers are closed to grip the ends of the wrapper to be twisted.

The mould-wheel A, has in it the recesses into which the caramels and their wrapping papers are passed. The said mouldwheel has movements of partial rotation imparted to it which may be effected by any suitable, or known, means such, for ex ample, as the Geneva mechanism usually employed in machines of this type. The roll of paper B is carried by the reel b the trunnions of which are mounted in supports 6 carried by a bar 5 connected to the framing C, of the machine, the paper being led from the said roll B, beneath a jockey-roller b capable of rising and falling, the paper being then brought upwards and passed over the roller 6 and then down and between rollers 72 and I), the roller 6 being driven intermittently to accord with the intermittent movements of the mould-wheel A. This may be efi'ected by a Geneva movement such as that hereinbefore referred to. The roller 6 gives the necessary grip upon the paper on the feeding roller 6 the said roller 6 being carried by a counter-weighted arm 6 so that the said roller can be held away from the rollers 12 when it is desired that the paper shall not be fed. The intermittent movements of the paper and of the mould-wheel A, in accordance with each other, are transmitted from the main driving shaft D by the drive (indicated at d), which operates the shaft a of the mould-wheel A, similarly to the manner in which the mould-wheel is operated, the shaft a also operating the paper-feed through the gear-wheels 6Z2, synchronously with the intermittent movements of the mould-wheel A, so that suflicient paper for a wrapper is presented in position before each recess in the mould-wheel, as it comes round, when the pusher E pushes the caramel together with the wrapper, into the recess, the said pusher E being operated from the main shaft D by a cam 6 (see Figures 4t and 5) on the said shaft D acting upon the roller 6 on one arm of the lever a mounted on the spindle e the other arm 6 of the said lever constituting, or carrying, the pusher E.

The caramels to be wrapped are fed into the trough F in which runs an endless belt f, or chain caused to travel intermittently, synchronously with the intermittent periods of rest of the mould-wheel A and the paperfeed, through the gearing, illustrated in Figures 1, 2, and 3, consisting of a drive 9 from the shaft D, operating the shaft 9 a bevel-wheel g which gears with another bevel-wheel f on the shaft f which has keyed to it the belt driving-pulley f The same shaft 9' carries a spur-wheel h which gears :with the pinion H (shown as being formed in the spindle h itself) which 0perates the grippers G and G hereinafter described, the motion for the two pairs of grippers being driven from the same spindle 7L After the pusher E has acted to push the caramel off the band 7 or chain through the opening 2' in the guide plate I and against the paper and then both the caramel and paper through the opening 2' in the opposite guide-plate 1 into the mould-wheel recess a which is, at that time, opposite the caramel and paper, the cutter J acts to cut off the amount of paper for the wrapper and, the caramel, being then covered on three sides by the wrapper so applied, the pusher E retires ready to repeat the same operation with the next caramel and wrapper when the next recess in the mould-wheel is presented in line with the said pusher. The paper thus applied is long enough to be wrapped around the caramel with any desired amount of overlap and is of a width to project beyond both ends of the caramel to a sufficient extent to allow of being twisted to complete the wrapping. The next partial rotation oi the mould-wheel brings the recess, with the caramel and wrapper in it, into the position in which the outstanding portions m, m of the wrapper pass against the stationary folder K as shown in Figures 6 and 7 which causes the first outstanding portion 00 to be partially bent over the fourth side of the caramel, a movable folder L being operated from the cam Z on the shaft D acting upon a roller Z on the lever Z turning on the pivot Z and drawn downwards by a spring Z and through the rod Z drawing down the folder L so that it folds the outstanding portion 50 of the paper in a double fold under the aforesaid partially bent portion a; as shown in Figure 7. When the mould-wheel A makes its next movement of partial rotation the part 7:: which forms a continuation of the stationary folder K concentric with the mould-wheel A, retains the wrapper in its folded position. If the part so of the wrapper be su'liicient to overlap the side of the caramel which it covers the overlapping portion can be folded down by any suitably actuated folder.

The twisting of the Wrapper projecting from the ends of the caramel is effected by the grippers (i and G shown clearly in elevations and plans in two positions in Figures 8, 9, l0 and 11. Figures 8 and 9 show ing the grippers in the open position and Figures 10 and 11 showing them in the closed position. Each gripper consistsof jaws (which may have roughened gripping faces) connected by a closing spring and pivoted at g to the spindle 7L3 and geared together by the segmental gears the tail end of one of the jaws of the gripper G being acted upon (to open the gripper jaws) by a projection (see Figure 2) on one arm of a bell-crank lever (keyed on the shaft 9 which is operated by a cam g on the main shaft D acting on a roller on the other arm of the said lever against the action of a spring for closing the jaws the other jaw of the said gripper having the opening motion conveyed to it through the segmental gear 9 The gripper i ii G is conveyed V spindle by a toothed secured to a shaft provided with toothed v. ieel it which with the lon pinion l 1 formed in the spindle 7c of the gripper The pinions long so that they remain alw Ti gear with the wheels )"L and ii as the grippers have to be mover longitudina ly towards each other to follow the shortening of the onus of the wrapper due to the twistr g.
